Ex.: Overflow of time counter description human readable description. Ex.: The time counter overflowed while computing delta increase pp formatter used to pretty print additional arguments. Ex.: The time counter overflowed while computing delta increase. Previous value %d. Delta: %d encoder decoder data encoding for this error. If the error has no value, specify Data_encoding.empty

unitSame as register_error_kind but allow errors to wrap other errors.
The encoding argument is a function which will be given the encoding of errors as argument so that you can encode errors in errors using a fixpoint.
Another difference with register_error_kind is that pp is mandatory.
val classify_error : error -> Sig.error_categoryClassify an error using the registered kinds
Catch all error when 'serializing' an error.
val json_of_error : error -> Data_encoding.jsonAn error serializer

val pp_info : Stdlib.Format.formatter -> error_info -> unitval get_registered_errors : unit -> error_info listRetrieves information of registered errors
